Claims (2)

1. Способ получения защитного полиуретанового покрытия, включающий смешение исходных продуктов: полиизоцианатного компонента в виде полиизоцианата на основе дифенилметандиизоцианата и гидроксилсодержащего компонента в виде простого полиэфира, содержащего три гидроксильные группы, в присутствии инертного растворителя - уайтспирита, отличающийся тем, что используют полиизоцианатный компонент 4,4’-дифенилметандиизоцианат с содержанием NCO-групп не менее 29,5 гр/100 гр, в качестве простого полиэфира используют лапролы с гидроксильным числом 32-37 мг кон/гр. дополнительно используют бутилацетат при следующем содержании исходных компонентов, мас.ч.:1. A method of obtaining a protective polyurethane coating, comprising mixing the starting products: a polyisocyanate component in the form of a polyisocyanate based on diphenylmethane diisocyanate and a hydroxyl-containing component in the form of a polyether containing three hydroxyl groups, in the presence of an inert solvent - white spirit, characterized in that the polyisocyanate component 4 is used, 4'-diphenylmethanediisocyanate with an NCO content of at least 29.5 g / 100 g; laprols with a hydroxyl number are used as the polyether 32-37 mg KOH / g. additionally use butyl acetate in the following content of the starting components, parts by weight: Полиизоцианат 26-32,5Polyisocyanate 26-32.5 Лапрол 5003 или Лапрол 4503 30-32,5Laprol 5003 or Laprol 4503 30-32.5 Бутилацетат 8,79-10,36Butyl acetate 8.79-10.36 Уайтспирит 22,9–26Whitespirit 22.9–26 при этом сначала смешивают гидроксилсодержащий компонент с растворителем, добавляют бутилацетат либо гидроксилсодержащий компонент смешивают со смесью из бутилацетата с уайтспиритом, а затем в полученную смесь добавляют полиизоцианат, синтез проводят при перемешивании до содержания массовой доли изоцианатных NCO-групп в форполимере 7,5-11,5%.first, the hydroxyl-containing component is mixed with the solvent, butyl acetate is added, or the hydroxyl-containing component is mixed with a mixture of butyl acetate and white spirit, and then polyisocyanate is added to the resulting mixture, the synthesis is carried out with stirring to the content of the mass fraction of isocyanate NCO groups in the prepolymer 7.5-11, 5%. 2. Способ получения защитного полиуретанового покрытия по п.1, отличающийся тем, что в качестве простого полиэфира используют лапрол 5003 или лалрол 4503.2. A method of obtaining a protective polyurethane coating according to claim 1, characterized in that laprol 5003 or lalrol 4503 are used as the polyether.
